  * This preloader uses a stack segment allocated in cluster 0, defined
- * by the seg_reset_stack_base and seg_reset_stack_size parameters in ldscript.
+ * by the seg_reset_stack_base parameters in ldscript, of size 0x10000 (64k)
  * - Processor 0 uses a larger stack:         64 Kbytes.
  * - Other processors use a smaller stack:    512 bytes.
- *     => the seg_stack_size cannot be smaller than 0x90000 bytes (576 K).
+ *     => the stack size cannot be smaller than 0x90000 bytes (576 K).
  * Those stacks can be used by both the preloader and the boot-loader code.
